sHlNeLE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 442,170, dated December 9, 1890.

Application filed October l, 1888.

ToaZZ whom it iii/ay concern:

Be it known that l, FRANK CHALLONER, of Omro, in the'county of lVinnebago and State of Visconsin, have invented certain new and useful Improvements in Shingle-Sawing Machines; and I de hereby declare that the following is a full, cle-ar, and exact description of the invent-ion, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Myinvention relates to that class of shinglemachines in which a rotary bolt-carriage,a circular track with movable sections for dropping the residuum of the shingle-bolts, commonly called spalts, two saws, and two tilting tables on opposite sides of the machine are employed.

Its main object is to facilitate graining the bolts or maintaining the direction of the grain nearly as practicable parallel with the plane of the saws.

It consists, essentially, of mechanism under the control of the operator for effecting that end, hereinafterspecifically set forth, and pointed out in the claims.

In the accompanying drawin like letters designate the same parts in the several figures.

Figui-el is a perspective view of a portion of a shingle-machine to which my improved tilting mechanism is applied. l `igs. 2, 3, and

4 are detail views of portions of the same on .are

an enlarged scale, Fig. 2 being alongitudinal section of a yielding coupling in the connecting-rod, Fig. 3 asimilar view of the vibrating step in which the tilting bar rests and of its adjustable support, and Fig. l: a horizontal section on the line at, Fig. 3.

Referring to Fig. l, A represents a portion of a rotary carriage; B, one of the supportingcolumns belonging to the frame-work of the machine; C, the tilting table, which is supported on the upper end of a tilting bar c, passing near its lower end through a slotted block D, attached to and capable of angular adjustment on a bracket projecting' from the adjacent column. The tilting bar c is free to vibrate in said slotted block, and its vibratory movement is adjustably limited by stop-bolts d.

Serial No. 236,912. [No model.)

The constrution and operation of the foregoing parts are like or similar lto thosein like or similar machines of the class hereinbefore referred to. At its lower end the tilting bar c rests in a vibrating step I, which is hinged on the pin e' in the upper bifurcated end of the screw E, as shown most clearly in Fig.

K is a bracket attached to and projecting horizontally from the adjacent column l, and formed with a vertical perforation for the reception of the screw E, and with a horizontal slot for the reception of a nut J,l\y means of which said screw is secured in said bracket and the tilting table is raised or lowered for the purpose of varying the thickness of the shingles.

To turn the screw slightly in bracket l for the purpose of adjusting the plane of vibration of the tilting bar and table and to prevent said screw from turning when so adjusted, I provide a segmental plate 7c', Iitted and adjustably att-ached to the face of bracket. K, as shown in Fig. 4, by means of bolts 7a2 k2 passing through horizontal slots in said plate. Upon its inner face the plate 7i: is provided with a tongue t, which passes through a vertical opening formed therefor in bracket K and engages with a vertical groove e in said screw E, as shown in Figs. 3 and l. The pin fi, on which the step turns, is formed with a passage, as shown in Fig. 3, extending from one end thereof to its bearing-face, and in its outer end is secured an upwardly-bent tube 1',by means of which the bearing of said step is supplied with oil.

Il is a shorthorizontal rock-shaft supported and bearing in a sleeve attached to the column B orany other convenient part of the frame of the machine. It is provided at one end with a crank-arm h, which is connected by the link h2 with the lower end of the tilting bar c. It is provided at the other end with a crank-arm lr', set at right angles tothe arm 7L and connected by a rod o g with one end of a tripping-lever F, which is fulcrumed to a vertically-adjustable block F adjacent to the periphery of the carriage A. The tripping-lever F has a vertical incline f at one end, and at the opposite end next to its connection with the rod g g it is formed with an upwardlyprojecting inclined extension f. The block F is adjusted vertically by means ICO said barrel with a head g2, and of spiral springs g3 g3, inserted between the ends of said bai'- rel and the opposite faces of said head g2, as shown in Fig. 2. The purpose of the elastic connection is to prevent injury to the tilting mechanism described or disturbance of its adjustment by any inaccuracy or variation in the throw of the tripping-lever F and of the tilting bar c.

The machine to which my improvements are applied is provided on the opposite side (not shown) with the counterpart of the tilting table and mechanism just described, one tilting' table being inclined inwardly and the other outwardly, so as to reverse the inclination of the blocks as they are dropped alteriiately thereon. rlhc machine is also provided with two saws. (Not shown.) The rim of the carriage Ai is provided adgacent to each bolt-receptacle with two sliding pins a d', placed near together, one a little above the other, so that the lower pin a, when moved outwardly, will engage with'the tripping-lever F on one side 0f the machine, and the upper pin a', when moved outwardly, will clear said tripping-lever F and engage with the other tripping-lever, which is set a little higher on the opposite side of the inachine.

It is obvious that any suitable device movable iiito and out of range wit-h the trippinglever F maybe employed in place of the 4pins et d', and that various changes in the details of my improvements may be made within the spirit of my invention.

Myimprovements operate as follows: Vhenever the saw-cuts are oblique to thegrain of the sliingle-bolt and it is desired to bring such cuts as nearly as practicable parallel with the grain, so as to produce straightgrained shingles, the operator thrusts one or both of the pins a. d outwardly as they pass him. The lower pin a', engaging the incline f of the tri pping-lever F, elevates the opposite end of said lever, and through the connecting-rod g g', arm 7i', rock-shaft H, and arm h throws the lower end of the tilting bar c ontwardly and reverses the inclination of the tilting table (l as the shingleblock is dropped thereon. The block or boltis then dogged in the usual manner in the position it assumes on said tilting tables, and is carried tothe saw, which cuts from the under side thereof a shingle with the butt at the same end from which the'butt of the preceding shingle was taken. As the pin a passes theinclined projection f on the other end of the tilting-lever it throws vthe lower end of the tilting bar c inwardly and returns the tilting table C to its first position. After passing said tilting-lever the pin a engages an inwardly-inclin ed guide T, iixed toa bracket or suitable support. projecting from the frame of the machine, and is forced by said guide inwardly out of. range of said tilting-lever, which it clears in the next and succeeding revolutions of the carriage until again thrown outwardly by the operator. If necessary, another butt may be cut from the same end of the same block by moving the upper pin a outwardly into position to engage and operate the tripping-leyer on the opposite side of the machine, in which case the operation just described is repeated, when the bolt passes the other tilting table and saw. A'similarinclined guide (not shown) on the opposite side of the machine automatically returns the'upper pin a. to its iirst position out of range with the tilting-lever which it is designed to operate. This operation, called graining, may be repeated in 'like manner until the cut made by the saws is as nearly parallel as practicable with the. grain of the block, and there being a set of pins for each block-receptacle in the carriage any or all of the blocks contained in the machine may be grained in the manner described.
